Purpose
=======

Don't display sales app icon in Odoo homepage when installing ecommerce (only website should be visible)
it's confusing to have sales icon  -> where do I manage my sales? In sales or in website? -> in website

Specfication
============

We need one new modules to add Sales menus to the homepage. Currently they come with "sale". So when installing "website_sale", we get them (because sale and account are dependencies of website_sale). We don't want that anymore. Along with that you need to replace modules in Apps menu:
sales menu items must be in the new sale_management module, no longer in sale

- create new app "sale_management"
- Currently 3 app icons when installing ecommerce (Sales, Invoicing, Website) -> too many icons, where to start? -> GOAL: Only 2 icons > Website, Invoicing
- new module to display Sales Icon (like account_accountant): "sale_management"
- move menu items to sale_management
- sale, sale_management: move app description, rewrite the manifest file
- sale, sale_management: move tour from sale > sale_management
- Changes in some dependency module "sale" > "sale_management" modules: event_sale, mrp_repair, pos_sale, report_intrastat, sale_crm, sale_expense, sale_stock, sale_timesheet, website_quote

Menu items to move 'sale' --> 'sale_management'
